Fond memories too, my second significantly used home computer (mainframes and
midrange at work) (first was Trs80 m1, many others that I did almost nothing
with)
Mine was the first pc/xt clone I found for under $1000. Eventually grew to

I think I briefly used one at university.
I wrote about it recently. Its startling price put the Apple Lisa,
launched the same year, into context:

The Lisa flopped partly
And 1 of the floppies (it may habe 3) was full height. So maybe someone was

got it all working it would be aomething of an 80s retro type

Tin-plate on copper would be likely, easy to solder-seal on. Al would not
solder on easily.
Tin does make a nice plating. Even HP made some lab/computing

I'm just guessing, but probably NP copper.
Earlier chips would have gold and later ceramic or black to save money.
With RAM being expensive it was common to take whatever you had and toss it

Well the latgest question I have is whether early NEC chips with any lida were
commonly used to populate tne 5162. And if your lids aren't gold plated, is the
lid aluminum or some related alloy?
